[0001] This utility model relates to the technical field of refrigerator door assembly, specifically an adjustment device for refrigerator door assembly. Background Technology

[0002] Existing hinges are widely used in furniture and appliances. The structure of an existing hinge generally includes a base installed on the refrigerator door, a fixed seat installed on the refrigerator body, and a transmission component hinged between the base and the fixed seat. The transmission component enables the base to open and close on the fixed seat, thereby enabling the refrigerator door to open and close on the refrigerator body.

[0003] However, the hinge structure described above has the following shortcomings in practical applications:

[0004] 1) For existing hinges, if it is necessary to add the function of adjusting the height, an adjustment component is generally added to the outside of the hinge. This increases the overall height of the hinge due to the added thickness of the adjustment component, which can only be used for very thick refrigerator doors and has no advantage for thin-door refrigerators.

[0005] 2) The existing hinges have added adjustment parts, which are complex in structure, inconvenient to operate, and prone to displacement during adjustment, resulting in poor adjustment effect and even affecting the assembly quality of the product. Utility Model Content

The base is provided with a door support, which is assembled on one side of the base. The door support is provided with a vertical adjustment component for adjusting the door assembly position. The vertical adjustment component includes an adjustment plate and an adjustment screw. One end of the adjustment screw passes through the adjustment plate and is connected to the door support. The other end of the adjustment screw is eccentrically rotatably connected to the adjustment plate. The adjustment plate is installed on the door support and moves up and down on the door support by rotating the adjustment screw, thereby driving the base to move up and down relative to the door. The two sides of the door support are provided with limiting protrusions to prevent the adjustment plate from rotating with the adjustment screw.

[0008] Based on the above optimization, the adjusting plate has a horizontal waist-shaped hole in the middle, and the adjusting screw has an eccentric wheel that is rotatably connected to the horizontal waist-shaped hole.

[0009] Based on the above optimization, the adjusting screw is provided with a riveting end that is riveted to the door bracket.

[0010] Based on the above optimization, the limiting protrusions are integrally formed on both sides of the door frame, and guide grooves for the guide adjustment plate to move up and down are formed between the limiting protrusions.

[0011] Based on the above optimization, the door support includes an installation part and a connecting part. The installation part is assembled on one side of the base and is integral with the connecting part in the form of a "7" shaped bracket. The inner groove of the "7" shaped bracket is adapted to fit and fit the door body. The adjusting plate is slidably connected to the outside of the connecting part. The adjusting screw has a riveting end that passes through the adjusting plate from the outside to the inside and is riveted to the connecting part.

[0012] Based on the above optimization, the adjustment plate is equipped with fixing screws for fixing the door bracket to the door body. One end of the fixing screw is rotatably connected to the adjustment plate, and the other end of the fixing screw passes through the adjustment plate and the door bracket in sequence and is threadedly connected to the door body.

[0013] Based on the above optimization, the door support has a longitudinal oblong hole for easy spatial movement of the fixing screw during vertical adjustment. When the fixing screw is loosened, it slides along the longitudinal oblong hole as the adjustment plate moves.

[0014] The advantages of this utility model are:

[0015] 1) By using the door bracket and the adjustment plate and adjustment screw of the upper and lower adjustment components, the adjustment plate can be moved up and down by rotating the adjustment screw, thereby realizing the upper and lower installation position of the refrigerator door. The structure is simple and easy to operate. Moreover, by adopting the structural characteristics of the door bracket, the total thickness of the refrigerator door is inside the door bracket, without increasing the total height of the hinge. It is suitable for the assembly of refrigerator doors of different specifications, and is reliable and practical.

[0016] 2) Under the action of the limiting protrusion of the adjustment plate, it is effectively ensured that the adjustment plate will not rotate during the adjustment period, thus affecting the installation position of the refrigerator door and ensuring the quality of product use.

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] According to the appendix Figures 1 to 6 As shown, the refrigerator door assembly adjustment device of this utility model includes a fixed base 1 installed on the cabinet and a base 2 installed on the door. A transmission component 3 is hinged between the fixed base 1 and the base 2 for opening and closing the fixed base 1 on the base 2. The base 2 is provided with a door support 4, which is assembled on one side of the base 2. The door support 4 is provided with a height adjustment component for adjusting the door assembly position. The height adjustment component includes an adjustment plate 5 and an adjustment screw 6. One end of the adjustment screw 6 passes through the adjustment plate 5 and is connected to the door support 4. The other end of the adjustment screw 6 is eccentrically rotatably connected to the adjustment plate 5. The adjustment plate 5 is installed on the door support 4 and moves up and down on the door support 4 by rotating the adjustment screw 6, thereby driving the base 2 to move up and down relative to the door.

[0025] In practical applications, the adjusting plate 5 has a horizontal waist-shaped hole 51 in the middle, and the adjusting screw 6 has an eccentric wheel part 61 that is rotatably connected to the horizontal waist-shaped hole 51 and a riveting end 62 that is riveted to the door bracket 4.

[0026] That is, rotating the adjusting screw 6 controls the up and down movement of the adjusting plate 5, thereby realizing the up and down installation position of the refrigerator door. The structure is simple and the operation is convenient.

[0027] Reference Figures 1 to 6 As shown in the figure, further detailed, the door bracket 4 includes a mounting part 41 and a connecting part 42. The mounting part 41 is assembled on one side of the base 2 and is integral with the connecting part 42 as a "7"-shaped bracket. The inner groove of the "7"-shaped bracket is adapted to fit and fit the door body. The adjusting plate 5 is slidably connected to the outside of the connecting part 42. The adjusting screw 6 has a riveting end 62 that passes through the adjusting plate 5 from the outside to the inside and is riveted to the connecting part 42.

[0028] The structural characteristics of the door bracket 4 using this structure mean that the total thickness of the refrigerator door is within the inner groove of the door bracket 4, without increasing the total height of the hinge. It is suitable for assembling refrigerator doors of different specifications and is reliable and practical.

[0029] Reference Figures 1 to 6As shown, the adjustment plate 5 is provided with fixing screws 8 for fixing the door bracket 4 to the door body. One end of the fixing screw 8 is rotatably connected to the adjustment plate 5, and the other end of the fixing screw 8 passes through the adjustment plate 5 and the door bracket 4 in sequence and is threadedly connected to the door body.

[0030] Furthermore, the door support 4 is provided with limiting protrusions 7 on both sides to prevent the adjusting plate 5 from rotating with the adjusting screw 6. The limiting protrusions 7 are integrally formed on both sides of the door support 4, and guide grooves for the adjusting plate 5 to move up and down are formed between the limiting protrusions 7.

[0031] When the refrigerator door needs to be adjusted up and down, simply loosen the two fastening screws and rotate the adjusting screw 6 to adjust the door height. Since the adjusting plate 5 and door bracket 4 are only separated by the adjusting screw 6 after the fastening screws are loosened, the adjusting plate 5 is effectively limited by the limiting flange 7, allowing it to move up or down along the guide groove without affecting the position of the fixing screw 8.

[0032] The door support 4 has a longitudinal waist-shaped hole 43 for the fixing screw 8 to move spatially when it is adjusted up and down. When the fixing screw 8 is loose, it slides along the longitudinal waist-shaped hole 43 as the adjusting plate 5 moves.

[0033] The longitudinal waist-shaped 43 holes provide sufficient space for the fixing screw 8 to move up and down during adjustment, facilitating operation and ensuring adjustment quality.

[0034] The above specific embodiments are only specific implementations of the present utility model with better effects. Any structure that is the same as or equivalent to the adjustment device for refrigerator door assembly of the present utility model is within the protection scope of the present utility model.
